KEN JEONG (Mr. Chow) first appeared as Asian mobster Mr. Chow in the 2009 mega-hit comedy "The Hangover," alongside Bradley Cooper, Ed Helms and Zach Galifianakis. The film became the highest-grossing R-rated comedy of all time and went on to make over $467 million worldwide, only to be trumped by "The Hangover Part II," which grossed $581 million worldwide.

Since his feature film debut as the doctor in "Knocked Up" in 2007, Jeong has gone on to a number of memorable roles in a series of successful comedies. Directed, written and produced by Judd Apatow, Jeong's first film grossed $219 million at the worldwide box office. In 2008, Jeong received his first major role as the villain, King Argotron, in "Role Models," opposite Paul Rudd, Seann William Scott and Christopher Mintz-Plasse. The film went on to gross over $90 million worldwide. The same year, Jeong appeared in two other major comedies: "Pineapple Express" and "Step Brothers."

Jeong's career path started off on a different course. He earned his undergraduate degree at Duke University and went on to attain his medical degree at the University of North Carolina. Jeong completed his Internal Medicine residence in New Orleans, all the while developing his comedy. In 1995, he won the Big Easy Laff Off. The competition, judged by former NBC President Brandon Tartikoff and Improv founder Bud Friedman, turned out to be his big break as Tartikoff and Friedman urged him to head to Los Angeles.

Jeong began performing regularly at the Improv and Laugh Factory, and was seen on a number of television shows, including "The Office," "Entourage" and "MADtv." It wasn't until his pivotal role as Dr. Kuni in "Knocked Up," though, that Jeong solidified himself as a feature film comedian. In 2006, he and comedian Mike O'Connell left a mark on YouTube as "Million Dollar Strong," a spoof rap duo. Since its posting in 2006, the video has garnered over 1 million views and Jeong and O'Connell have been tapped by MTV Films to write and star in the film version.

Jeong can currently be seen as series regular Senor Chang, alongside Joel McHale and Chevy Chase, on NBC's hit comedy "Community," now in its fourth season.

On the big screen, he most recently starred with Dwayne Johnson and Mark Wahlberg in director Michael Bay's actioner "Pain & Gain." His recent feature projects also include the hit comedy "The Muppets." Upcoming, Jeong will lend his voice to the animated family comedy "Turbo."

Jeong's additional credits include roles in "The Zookeeper," "Transformers 3: Dark of the Moon," "The Goods: Live Hard, Sell Hard" and "All About Steve." He has also appeared in numerous Stand Up 2 Cancer PSAs and hosted the 2011 Billboard Music Awards.
